THE first asylum seekers to be affected by the federal government’s freeze on refugee processing arrived on Christmas Island yesterday.About 50 people, believed to be Afghans, will have to wait six months in detention before their protection claims are considered.Announced nine days ago, the Rudd government’s freeze applies to all boat arrivals from Afghanistan and Sri Lanka. The “evolving” situation in the two countries could allow the safe return of people to their homelands, it said.Just as the new arrivals were ferried on to the island, a plane carrying about 60 young asylum seekers left for the mainland.Detention staff saw off the teenagers, mostly from Afghanistan, who arrived in Australian waters without parents or guardians.
